Be a nice neighbor, try to reply with whatever headers we have, don't fail
completely because of a single missing header.

Transfer data is timestamp-based, previously it always had and used headers,
no we can go via a small cache (we don't want it to grow or be stored forever).
Otherwise it's unable to do the job:

It's there since 423c7883b8, but looks like it
never changed anything, the same thing is done six lines above and tgtBlock is
not changed since.

It's important to have the same chain configuration for all tests.
Otherwise, a mismatched hardfork configuration is used to dump/restore
the basic chain.

Drain the channel only if it has pending events. This avoids trying to
read from an already-empty channel.

They will be returned to pool when disconnected anyway. On a smaller network
this can make a difference because there are not a lot of addresses in the
pool usually.

It's impossible to maintain a 4K line. I'm not even sure new table works good
enough, but at least it's per-hardfork.

Function doesn't make much sense here. The change is rather trivial and this
is not expected to be used by external code, so no deprecation.

Differentiate released and stable ones from test-only not-yet-ready and such.
Enabled only stable ones by default to avoid surprises in private networks
when some beta hardfork is made available with some node release.
Fixes#3719.

It's not supposed to happen, but if blockfetcher goes wild and calls this
twice it can ruin the system, so better safe than sorry.

blockFetcherFin is closed by the block fetcher, so it will forever return
something in this loop making it an infinite loop, creating useless load
and affecting normal node operation.

Consider 10-node network. FanOut is 6 for it. optimalN is 12. But it's a
10-node network, you can't have more than 9 peers there. So adjust the formula
for netSize-1.

We can have _a lot_ of these in the log, but the only reason they happen is
because we're trying to interpret length before checking for reader error,
CMDVersion is just 0.
